Mullein (Verbascum thapsus) leaves and flowers are a premier, clinically validated respiratory demulcent and expectorant. It is rich in soothing mucilage polysaccharides, saponins (which thin thick mucus), and verbascoside (a powerful anti-inflammatory polyphenol). The mucilage coats and protects raw, irritated airways to calm spasmodic coughs, while its saponins stimulate expectoration to clear congested bronchial passages.
Educational information only — never stop or change a prescribed medication without talking to your prescriber first.
CRITICAL: Always strain mullein leaf tea through a fine paper coffee filter or tight cloth to remove its tiny, irritating plant hairs, which can otherwise trigger throat itching. Avoid topical ear oil if there is any suspicion of a perforated eardrum.
